Comparative evaluation of clinical, hematological, and echocardiographic parameters in NSTE-MI patients undergoing CABG versus PCI

Non-ST-segment elevation myocardial infarction (NSTE-MI) represents a clinically significant form of acute coronary syndrome (ACS), encompassing a heterogeneous group of patients with varying degrees of myocardial ischemia and injury.[1] Unlike ST-segment elevation myocardial infarction (STEMI), NSTE-MI is not characterized by persistent ST-segment elevation on the electrocardiogram, but is nonetheless associated with elevated cardiac biomarkers indicative of myocardial necrosis.[2] It often reflects subtotal coronary artery obstruction or severe stenosis, and carries a considerable risk of short-and long-term adverse cardiovascular outcomes, especially in patients with extensive atherosclerosis, diabetes, or left ventricular dysfunction.[3] Optimal management of NSTE-MI hinges on timely risk stratification and appropriate selection of a revascularization strategy.Both the European Society of Cardiology (ESC) and American College of Cardiology/ American Heart Association (ACC/AHA) guidelines recommend an early invasive approach for high-risk patients.[2,3] The choice between percutaneous coronary intervention (PCI) and coronary artery bypass Ad dress for Cor res pon den
